Cereus identification and need advice.
A couple of weeks ago a parent of a student I teach was nice enough to bring me a plant that she picked up from a friend of hers who is a master gardener. She said he told her it was a Night Blooming Cereus. The plant looks like it has gone a few years without replanting and also looks quite awkward. Some of the branches hang down over the edge of the pot and fit it very closely now.
I'm first wondering exactly what it is - I have looked a lot and I'm not very sure about it. I thought about repotting it (the pot doesn't have a good base so I need to put it in something where it won't leak when watered). So what could I do with this? Should I cut off some of these limbs and start them in new small pots? Any advice on this? It looks like a lot of branches have been cut off it in the past.
